Frequently Asked Questions
How does the calculator handle time rollovers?
All time values are converted to total seconds for the calculation. The result is then converted back to hours, minutes, and seconds, automatically handling rollovers (e.g., 70 seconds becomes 1 minute and 10 seconds).
Can I calculate negative time?
Yes. If you subtract a larger time from a smaller one, the result will be displayed with a negative sign. A warning will also appear to notify you.
